Proper insulation supports energy efficiency, comfort, and lowers utility bills in your home. However, incorrect insulation installation undermines these benefits. Avoid these common mistakes to save time, money, and frustration.
- Choosing the Wrong Type of Insulation. Not all insulation works the same. Each type—fiberglass, spray foam, cellulose, or rigid foam—offers unique properties and suits specific areas. For example, spray foam reaches hard-to-access spaces, while fiberglass works better for open walls. Choosing the wrong type results in subpar performance and higher energy bills.
- Skipping Air Sealing. Insulation reduces heat transfer, but it doesn’t stop air leaks. Failing to seal gaps, cracks, and openings allows drafts to compromise your home’s energy efficiency. Use caulk or spray foam to seal these areas before adding insulation.
- Compressing Insulation Material. Many homeowners compress insulation to fit tight spaces, but this reduces its effectiveness. Insulation relies on trapped air pockets to prevent heat transfer. Compression removes these pockets and decreases its R-value (thermal resistance). Always let insulation expand fully to maximize efficiency.
- Not Accounting for Moisture Control. Moisture degrades insulation and causes mold or mildew to form. Skipping vapor barriers or ignoring existing moisture problems ruins insulation efforts. Install a vapor barrier when needed and dry the space completely before adding insulation.
- Overlooking Building Codes and Safety Standards. Every area enforces building codes and safety guidelines for insulation installation, including fire resistance and clearance around electrical wiring. Ignoring these rules creates safety hazards and leads to costly corrections. Research and follow local codes before starting your project.
Avoiding these mistakes ensures your insulation works as intended, keeping your home energy-efficient and comfortable. Proper planning, attention to detail, and adherence to guidelines prevent costly repairs and wasted effort. If you’re looking for insulation installation done right, give us a call.
